Re: Robot radio blocking ports

I don't have access to a robot at present, but the key message was "connection refused" when attempting to connect to port 22 of the RoboRIO.

We've already proven that our radios are blocking port 22 (ssh) by connecting a test laptop running Linux via WiFi to the radio which is in turn connected via Ethernet cable to the RoboRIO. When we remove the radio from the mix and go direct we can get into port 22 of the RoboRIO just fine. We are addressing the RoboRIO by its assigned IP address in both cases.

In the meantime, we've had to program the robot via USB cable. Note that we can bring up the webdashboard and operate the robot via WiFi just fine (since port 22 is not used in those cases).

Thanks guys for offering assistance/insights.
